Yes, the 6.7L engine uses the same process to regenerate the DPF as the 6.4L trucks do. The only difference that I'm aware of is that the left side cylinders are the only ones that do it, as the right side is what feeds the EGR system.

I've only seen one regen cycle with this truck and it appears to take less time than my 6.4L did. The downside is that the message doesn't stay on the screen so you have to guess based on the MPG change when it's done.
